Question

difference between attached growth process and suspended growth process

Answer 1

Biological filters can also be used in denitrification, combined with a suspended or attached growthsecondary nitrification treatment. The main differences between aerobic and anoxic filters are the absence of aprocess air system, the material's size and the input of external carbon if required.

Answer 2

Difference between attached growth process and suspended growth process:

Attached growth process:

• A type of waste water treatment in which microorganism responsible for conversion of nutrient is attached to an inert material such as rock.
• It is an anaerobic process.
• It is commonly called as anaerobic filter process.

Suspended growth process:

• A type of waste water treatment in which microorganism responsible for treatment are suspended in liquid form in the tank.
• It is an anaerobic process.
• It is commonly called as Anaerobic contact process
